To. ALL wHoM 1T MAY oouennn:V

Be it known that I, TUNIS vBURYIY'IE, of FondduLac, in the county of Fond du Lac, and Stute of Wisi cousin, -huvc in'vcnted certain new and useful lmprovements in Churns; and I do hereby declare that the following is a full, clear, und, exact description thereof, reference being hadto thcaccompanyiug drawings making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur v To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention consists in a novel method of constructing a churn, whereby the temperature of the cream may be regulated as desired, and in mounting the same on un oscillating platform, in such a manner that the .swinging of a pendulum, or weight attached to the platform, shall communicate motion to thechurn.

Figure 1 isa vertical section; and

Figure 2, a transverse vertical sect-ion of the churn.

A represents the churn, which l construct in the form of an oblong rectangular box, as represented in iig. 1.V This box may be made of tin or other suitable metal, orthe body may be made of wood, provided' the bottom be of metal` This box A. is provided with a suitable opening, with a cover', m, at its top, and has a spout, c, for the escape of the buttermilk. Underneath this churn vor box A is secured a false bottom, with a space between it and the bottom ofthe box, thus forming a shallow chamber, B, under the box, into which hot or cold water may be poured, through the funnel a, for the purpose of raising or lowering the temperature or" the cream as may be desired. This chamber B is provided with a coclt, u, orvwith asilnplo tube for drawing oil` the water when necessary. In the centre of the -box A is placed a grate, I), shown more'clearly in iig; 2. This grate is made of a width equal to the opening in the top of the box, which, in this cass, extends nearly across the box, the spaces between the sides of the rack or grate and the sides of the box, beiuglilled by a perforated plate, L, as shown in iig. 2; the grate being arranged to be lifted out for the purpose of cleaning the churn. The churn thus constructed is mounted on a platform, L, suspended or pivoted on a rod, 0, to an upright frame, E, as shown in lig. 1, there being, of course, two of the supports E, one on each side. To the platform L, on each side, is attached' rigidly a bur or rod, c, reaching nearly to the bottom ol` the frame E. A box, D, is arranged between these bars C, so that it can be raised or lowered at will, it being held in place by loops which cla-sp around the bars Eand by a rod inserted through holes i'n the bars, underneath the bor. By these means the box D may bc raised or lowered as desired, thus making the oscillations more 'or less rapid, according to the amount and condition of the cream in the churn. This box D may be of any desired size, but should be made shallow, so'as not to occupy any more space, vertically, than is necessary. Across the top of the box D is arranged a. seat, s, as shown in iig. 1. I

The operation is as follows: The cream to he churned is placed in the boxA, and the latter is then placed on the platform L. The temperature is then regulated by pouring hot or cold water into the chamber B through the tube a; a thermometer, t, being attached to the box A to Vindicate the temperature. Weights ofany kind are previously placed in thc box D, which serve to keep the platform and churn in a horizontal position, and prevent them from tipping over. By pushing the box D, a swinging or oscillating motionl is imparted to it, and thereby the platform and churn are made to rock to and fro; thus dashing the cream to and fro in the box, and causing it to rush violently through the grate I), and dash against the ends, whereby the globules are broken, and the butter produced or separated 'from the' milk. nstead of placing weights in the box D, a child may be seated on the seat s, and, either by the aid of others or'by its own efforts, may impart a swinging motion to the apparatus; and thus the labor of churning may bcturned into a source of amusement, and be performed by children Who have not sufficient strength to operate the ordinary dasher churn.

Having thus described my invention, what I claim, isv 1. The churn A, provided with the water-chamber B at its bottom, and the removable grate 6, and having the tubes a, c, and n, arranged asl shown and described. 2. In combinationwith thc platform L, piroted to the supports E, I claim the pendulum rods (l2/and the adjustable box D, or it equivalent, arranged to operate as set i'orth.
